Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology, and in particular to an adhesive coating device that can solidify rapidly. Background Technology

[0002] Glue coating equipment is a device consisting of glue storage, conveying rollers, and coating rollers, which can evenly apply glue to the surface of paper. The glue needs to solidify quickly because this improves production efficiency, allows the coated paper to proceed rapidly to the next process, enhances product quality and stability, and ensures close integration between the coating process and other processes, conforming to the characteristics of efficient and continuous automated production.

[0003] Most rapid curing processes involve bringing the coating roller and the heating roller into contact. As the paper moves between the coating roller and the heating roller, the adhesive cures much faster due to the heat from the heating roller, allowing the label to adhere firmly to the product surface.

[0004] In existing technologies, some coating equipment often suffers from inconsistent paper thicknesses between different batches or different sections of the same sheet. This thickness difference significantly impacts the coating effect as the paper passes between the coating and heating rollers. Thicker paper areas increase the gap between the coating and heating rollers, reducing the contact pressure. Consequently, the adhesive receives less heat in these areas, slowing its setting. Conversely, thinner paper areas experience a smaller gap and increased contact pressure. This causes the adhesive to absorb excessive heat, leading to overheating and uneven setting, thus affecting the overall coating quality. Therefore, to address these shortcomings, a fast-setting adhesive coating device is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fast-curing adhesive coating device. This device aims to improve the problem in existing technologies where changes in paper thickness cause alterations in the contact pressure between the coating roller and the heating roller, resulting in abnormal adhesive curing speed and quality degradation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fast-curing adhesive coating device includes a support frame. Two conveying rollers are rotatably connected to the left side of the support frame. A power-providing drive assembly is fixedly connected to the left rear end of the support frame, with the drive end of the drive assembly fixedly connected to the rear side of the top conveying rollers. A coating roller is rotatably connected to the bottom right side of the support frame. A glue storage roller is fixedly connected to the bottom inside the support frame. Two receiving holes are opened inside the right side of the support frame. A fixing rod is fixedly connected inside the receiving holes. A strong spring is sleeved on the outside of the fixing rod. A sliding block is slidably connected to the outside of the fixing rod. A heating roller is rotatably connected to the adjacent side of the two sliding blocks. A dust removal cleaning assembly is fixedly connected to the right inside of the support frame.

[0008] Furthermore, a receiving block is fixedly connected to the front top of the support frame, a rotating rod is fixedly connected to the inside of the right side of the receiving block, an electric push rod is fixedly connected to the top of the receiving block, an L-shaped rod is rotatably connected to the driving end of the electric push rod, a guide hole is provided on the outside of the L-shaped rod, a connecting column is fixedly connected to the right end of the guide hole, and an adjusting rod is rotatably connected to the rear end of the connecting column.

[0009] Furthermore, the drive assembly includes a motor, the front end of which is fixedly connected to the left rear end of the support frame. Two gears are rotatably connected to the left front end of the support frame. A drive wheel is rotatably connected to the bottom left rear end of the support frame. The front end of the drive wheel is fixedly connected to the rear end of the bottom conveying roller. A driven wheel is rotatably connected to the right rear end of the support frame. A pulley is sleeved on the outside of the drive wheel and the driven wheel. The front end of the driven wheel is fixedly connected to the rear end of the coating roller.

[0010] Furthermore, the two gears are meshed, and the rear end of the gear is fixedly connected to the front end of the conveying roller.

[0011] Furthermore, the cleaning assembly includes a carrying block, which is externally fixedly connected to the inside right side of the support frame. The carrying block has an open movable hole inside, and a cleaning plate is fixedly connected to the bottom of the movable hole. A sliding rod is slidably connected inside the carrying block, and a telescopic spring is sleeved on the outside of the sliding rod. A second cleaning plate is fixedly connected to the bottom of the plurality of sliding rods.

[0012] Furthermore, one end of the strong spring is fixedly connected to the inside side of the receiving hole, the other end of the strong spring is fixedly connected to the top of the sliding block, and the outside of the sliding block is slidably connected to the inside of the receiving hole.

[0013] Furthermore, the outer surface of the second cleaning plate is slidably connected to the inside of the movable hole, and the bottom end of the second cleaning plate is in contact with the top end of the first cleaning plate.

[0014] Furthermore, the outer part of the L-shaped rod is slidably connected to the inside of the receiving block, and the inner part of the guide hole is slidably connected to the outside of the rotating rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when coating paper, the sliding block heating roller and coating roller are brought into close contact by the adaptive force of a strong spring. When a thicker area of ​​the paper passes through, the spring is compressed to a certain extent, but the appropriate pressure between the heating roller and the coating roller is still maintained, so that the glue can obtain a stable heat supply. This avoids the problem of slow glue solidification speed caused by increased gap and reduced contact pressure, thereby ensuring stable heat transfer and improving the uniformity of glue solidification in the entire coating operation. In addition, the cleaning component cleans the dust on the paper before coating, which can avoid the adverse effects of dust particles on the glue coating quality.

[0017] 2. In this utility model, by activating the electric push rod, the L-shaped rod drives the guide hole to move outside the rotating rod, which in turn causes the adjusting rod to move up and down. This ensures that the paper maintains appropriate tension when passing through the coating roller and the heating roller, avoiding inconsistent glue thickness caused by paper wrinkles or uneven tension.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 3 This utility model provides an embodiment of a fast-curing adhesive coating device, comprising a support frame 1, which serves as the supporting structure for the entire device. Two conveying rollers 2 are rotatably connected to the left side of the support frame 1. These two conveying rollers 2 cooperate to provide power and support for paper conveying. A drive assembly providing power is fixedly connected to the left rear end of the support frame 1. The drive assembly is the power source for the entire device, and its drive end is fixedly connected to the rear side of the top conveying roller 2. The drive assembly includes a motor 3, which is the core power component. The front end of the motor 3 is fixedly connected to the left rear end of the support frame 1. Two gears 4 are rotatably connected to the left front end of the support frame 1. These two gears 4 are meshed, ensuring synchronous rotation. The rear ends of the gears 4 are fixedly connected to the front ends of the conveying rollers 2, allowing the gears 4 to accurately drive the conveying rollers 2 during rotation, thereby achieving stable paper conveying. A drive wheel 5 is rotatably connected to the bottom left rear end of the support frame 1. The front end of the drive wheel 5 is fixedly connected to the rear end of the bottom conveying roller 2. When the bottom conveying roller 2 rotates, the drive wheel 5 rotates synchronously.

[0027] A driven wheel 6 is rotatably connected to the bottom right of the rear end of the support frame 1. A pulley is fitted around both the driving wheel 5 and the driven wheel 6. Through the transmission of the pulley, the rotation of the driving wheel 5 is transmitted to the driven wheel 6, thus driving the driven wheel 6 to rotate. The front end of the driven wheel 6 is fixedly connected to the rear end of the coating roller 7, so that the rotation of the driven wheel 6 drives the coating roller 7 to rotate, preparing for adhesive coating. A coating roller 7 is rotatably connected to the bottom inner right side of the support frame 1. During rotation, the coating roller 7 cooperates with the glue storage roller 8 to complete the adhesive coating work on the paper. A glue storage roller 8 is fixedly connected to the bottom inner interior of the support frame 1, and the glue storage roller 8 is used to store adhesive.

[0028] Two receiving holes 9 are formed inside the right side of the support frame 1. A fixing rod 10 is fixedly connected inside the receiving hole 9, and a strong spring 11 is sleeved on the outside of the fixing rod 10. The strong spring 11 provides spring force and rebound force. One end of the strong spring 11 is fixedly connected to one side inside the receiving hole 9, and the other end is fixedly connected to the top of the sliding block 12. This connection method ensures the stability and reliability of the spring. The sliding block 12 is slidably connected to the outside of the fixing rod 10. The sliding block 12 can slide smoothly on the fixing rod 10, and the external slidable connection of the sliding block 12 to the inside of the receiving hole 9 restricts the movement of the sliding block 12 within a certain range. A heating roller 13 is rotatably connected to the adjacent side of the two sliding blocks 12. The heating roller 13 is in close contact with the coating roller 7 under the action of the strong spring 11, providing heat for the rapid solidification of the adhesive.

[0029] A dust removal cleaning component is fixedly connected to the right end of the support frame 1. This component effectively removes dust from the paper, improving the quality of glue application. The cleaning component includes a carrier block 14, which is externally fixedly connected to the right side of the support frame 1. The carrier block 14 has an internal movable hole 15, providing additional space. A cleaning plate 16 is fixedly connected to the bottom of the movable hole 15. A sliding rod 17 is slidably connected inside the carrier block 14, allowing it to slide freely within the block. A telescopic spring 18 is fitted around the sliding rod 17, providing elastic restoring force during its movement. A second cleaning plate 19 is fixedly connected to the bottom of the sliding rods 17. Driven by the sliding rods 17, the second cleaning plate 19 slides within the movable hole 15, with its bottom contacting the top of the first cleaning plate 16. When paper passes between the first cleaning plate 16 and the second cleaning plate 19, dust on the paper is effectively removed.

[0030] Reference Figure 2 , Figure 4 and Figure 5A receiving block 20 is fixedly connected to the front top of the support frame 1, providing additional space and support. A rotating rod 21 is fixedly connected to the inside right side of the receiving block 20; the rotating rod 21 is a fixed shaft. An electric push rod 22 is fixedly connected to the top of the receiving block 20, acting as a power adjustment device capable of generating linear motion. An L-shaped rod 23 is rotatably connected to the drive end of the electric push rod 22. A guide hole 24 is provided on the outside of the L-shaped rod 23, and the inside of the guide hole 24 is slidably connected to the outside of the rotating rod 21. This slidable connection allows the L-shaped rod 23 to move stably along the direction of the rotating rod 21 during movement. The outside of the L-shaped rod 23 is slidably connected to the inside of the receiving block 20, which restricts and guides the movement of the L-shaped rod 23. A connecting post 25 is fixedly connected to the right end of the guide hole 24, transmitting the movement of the guide hole 24 to the adjusting rod 26 at the rear end. An adjusting rod 26 is rotatably connected to the rear end of the connecting column 25. The adjusting rod 26 can move up and down under the drive of the connecting column 25, thereby ensuring that the paper maintains a suitable tension when passing through the coating roller 7 and the heating roller 13, and avoiding inconsistent glue thickness caused by paper wrinkles or uneven tension.

[0031] Working principle: First, the motor 3 is started, which drives the top conveyor roller 2 to rotate. Since the two gears 4 are meshed and fixedly connected to the front ends of the two conveyor rollers 2 respectively, the rotation of the top conveyor roller 2 drives the bottom conveyor roller 2 to rotate synchronously through the gears 4, realizing the paper conveying. At the same time, the drive wheel 5 fixedly connected to the rear end of the bottom conveyor roller 2 rotates accordingly. The drive wheel 5 drives the driven wheel 6 to rotate through the belt pulley. The driven wheel 6 drives the coating roller 7 to rotate. During the paper conveying process, when the paper passes through the coating roller 7 and the glue storage roller 8, the glue on the glue storage roller 8 is coated onto the paper. During this process, the strong spring 11 plays a role. One end of the strong spring 11 is fixed inside one side of the receiving hole 9, and the other end is fixed to the top of the sliding block 12. The sliding block 12 slides on the fixed rod 10 and slides outside inside the receiving hole 9. The heating roller 13, which is rotatably connected to the two sliding blocks 12 on the adjacent side, is in close contact with the coating roller 7 under the adaptive force of the strong spring 11. When the thicker areas of the paper pass through, the spring will be compressed to a certain extent, but it can still maintain a suitable pressure between the heating roller 13 and the coating roller 7, so that the glue can obtain a stable heat supply and avoid the problem of slow glue solidification speed caused by increased gap and reduced contact pressure. This ensures stable heat transfer and improves the uniformity of glue solidification in the entire coating operation.

[0032] Before the paper reaches the coating roller 7, the cleaning assembly cleans the paper of dust. A carrier block 14 is fixed inside the support frame 1 on the right side. A cleaning plate 16 is fixedly connected to the bottom of the movable hole 15 inside the carrier block 14. A sliding rod 17 slides inside the carrier block 14 and is externally fitted with a telescopic spring 18. Multiple cleaning plates 19, with their bottoms fixed to the sliding rods 17, slide within the movable hole 15 and contact the top of the cleaning plate 16. When the paper passes between the cleaning plate 16 and the cleaning plate 19, the dust on the paper is cleaned, preventing dust particles from adversely affecting the quality of the adhesive coating.

[0033] In addition, when the electric push rod 22 is activated, the drive end of the electric push rod 22 drives the L-shaped rod 23 to move. The guide hole 24 on the outside of the L-shaped rod 23 slides outside the rotating rod 21, so that the L-shaped rod 23 slides inside the receiving block 20. The connecting post 25 fixed at the right end of the guide hole 24 drives the adjusting rod 26 to move up and down, which can ensure that the paper maintains a suitable tension when passing through the coating roller 7 and the heating roller 13, and avoid the situation of inconsistent glue thickness caused by paper wrinkles or uneven tension.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
